Ivanka did not publicly announce the gender while she was pregnant because she is "superstitious," she told Fit Pregnancy, but she did enjoying playing a good prank on her husband, New York Observer owner Jared Kushner.

"I had a long running joke/prank with my husband, where I told him the only thing he would have to do the whole pregnancy is pack the bag for the hospital," she told the mag.

"He initially thought I was joking, but I kept going with the joke and he became very nervous about it. He kept telling me, 'I'm happy to do this, but you're going to be unhappy with what I pack,'" she recalled. "'I'm going to pack the wrong things; some of this stuff, I don’t know what it means. You know the nursing bra? I have no idea what that is.'"

"I finally told him that I’d been packed for three weeks and not to worry about it," she said. "Come on, please, especially with a guy — it wouldn’t have worked and he is 100 percent correct that he would have packed all the wrong stuff. But I had some fun with him for a little while."
